The development of nanoparticle reinforced composites is presently one of the most promising areas in materials science and engineering. Carbon nanotubes and other nanoparticles have the potential to greatly enhance the properties of composites when combined with traditional reinforcements such as carbon-, glass-, and aramid-fibers.
By combining nanoparticles with traditional reinforcement materials, multiscale composites with superior properties to that of regular composites can be produced. This research will focus on the dispersion of nanoparticles into polymers to produce composite materials for high velocity impact applications. Carbon nanotubes have extremely good energy absorption properties, which make them an excellent candidate as impact modifiers for epoxy resins. Nanotubes act as energy absorbers that dissipate the impact energy and stop the propagation of cracks, significantly increase the toughness of the resin system.
The following areas will be investigated to successfully produce multiscale composites for impact applications. (1) Dispersion and exfoliation of nanoparticles are a major concern due to the challenges that exist with the formation of agglomerates during the mixing of nanoparticles with the resin matrix. (2) With the addition of nanoparticles to the resin matrix there is a dramatic increase in the viscosity of the resin. This poses a problem with the processing of multiscale composites, as it will be difficult to achieve good wetting of the fibers with a very high viscosity resin matrix. (3) The effects of nanoparticles on the mechanical and thermal mechanical properties of the resin matrix system need to be fully evaluated and understood.
